On its Main Screen, Solar Fire has a constantly updated display of the current Ascendant and Midheaven for whatever location is currently selected as the default place. This is the Current Chart Preview, with the title Event Chart. When you first install Solar Fire, this default place will probably not be set to the place where you currently live. It is recommended that you set the default place to the location where you are currently living, so that the displayed Ascendant and Midheaven will be correct for your own location. Solar Fire also uses the default place that you set as a “first guess” whenever you choose to relocate a chart to a new location. If this is set to your current location, then this guess will probably often be correct, and this will save you from having to enter new location details needlessly.
>> To set the default place
1.Click on the Place box of the "Date and Place" status bar on the Main Screen; if you have not set it, it will default to New York, New York. 
2.If your current location is one that is already listed in the list of Favorite Places, then select it with the mouse.
3.Otherwise, click on the Add button to open the Atlas and either find your location or enter a new location. See Using the ACS Atlas for full instructions on choosing a place from the Atlas.
4.Once your location appears on the list of favorite places, then select it with the mouse and click the Set as Default button.
5.Then click on the Save button to return to the Main Screen.
The location shown in the status bar at the top of the Main Screen will now show the newly saved location, and the Ascendant and Midheaven will be correct for this location.
You will need to update the default place details in the same way whenever you move with your computer to a new place.
